The firehose is the easy part; the filter is the product. This guide covers Forecite's filter model end to end — the four tag dimensions, ticker and provider filters, and the watchlist semantics that make saved views composable.
Four dimensions, one rule
Topic, market, country, and sector. Values within a dimension OR together; dimensions AND together. 'Earnings OR guidance, in US equities, in biotech' reads exactly the way you'd say it out loud.
Watchlists as base filters
A watchlist saves a filter as your default lens, and the URL can override it one axis at a time — swap the tickers while keeping the watchlist's tags, or clear a single dimension explicitly. Save the result as a new watchlist when a temporary view earns permanence.
